Request for Opinions on Watch Authenticity

Dear all,

I am considering purchasing a particular watch, but there are certain aspects that do not seem quite right to me. As such, I decided to seek the opinions of others.

What are your thoughts on the watch, particularly without seeing the movement? I am nearly certain that it may be a replica due to some subtle details, and the inscription "antimagnetic" on the dial is often a red flag for me when evaluating vintage Omega watches. However, I have come across some genuine vintage Omega models from the 1950s and 1960s that also feature "antimagnetic" on the dial.

Any insights would be greatly appreciated.

Thank you all for your time and assistance.

That is fake. The nomenclature you see on the case back should be inside of the case back not outside. That and that model never existed.

+1. I don't think this is authentic.
